Titaniumdrew's tutorial: www.youtube.com The chords are: D - D4 | C | Am | G At the C chord the hammer-on is on the 2nd fret on the D-string. Then you transition to the Am chord by fingering the 2nd fret on the A string and then fingering the root of Am, which is of course the open A string itself. In Am you do the same hammer-on as you did in C. And finally in G you hammer-on the second fret on A, before releasing it and fingering the open A string as a transition back to D. The song is played in standard tuning using a capo on the first fret. Everything talked about in the video is relative to the capo.
